Original application filed April 2, 1921,, Serial. No. 458,105. Dividedand this application flled August 1,

' 1922. Serial- No. 578,982.

This application is a divisional of my pending application Serial No.458,105, filed a range.

The present invention has as its object to provide a range havingvarious features of novelty and advantage.

In accordance with the present invention, the framework of the range,for the most part, is formed of irons angular in trans verse section;the cover plates and panels are formed of sheet metal pressed or bent,into the desired shape, and the parts are so 1 arranged and assembledthat practically all bolts, rivets orother means for securing-the partstogether are hidden from View; consequently the range presents a very.pleasing 2b ,and neat appearance and, furthermore, there "beingnoexposed bolt heads, or the like,

about which grease or other foreign matter can accumulate, it is veryeasy to kee the range in a clean and sanitary condltion.

Since the range is almost entirely made up of light metal parts, whichmay be cheaply and easily assembled, a very economic structure ispresented, while at the same time the parts are so arranged and securedtogether that the range has the necessary rigidity and strength.

In the accompanyino drawings;

Fig. 2 is a perspective view of the skeleton or framework'of the range;

. Fig. 3 is a vertical sectional view taken through the back of therange on substantially line 3-3 of Fig. 4, the shelf and heating unitthereon being in central section and the oven being omitted;

Fig. 5 is a sectional view on line 55 of April 2nd, 1921, coveringimprovements in Fig. 3 and shows the manner in which one of the endpanels is assembled on the frame.

From Fig. 1 it will be seen that in general arrangement the range has abody port1on a supportedon legs I) and provided with a to plate acarrying electrical hot plates (Z. tising from the rear edge of the bodyportion is a back e and extending from this back and spaced above thetop plate is an oven f. Alongside of the oven is a shelf 9 which mayalso be provided with a hot plate 2'.

The construction of the framework of the range will be most clearlyunderstood by referring to Fig. 2. It will be seen that the frame forthe body portion of the range comprises two similar rectangular members10 and 11, each formed of angle iron, and

corner brackets securing these members in spaced relation, the rearcorner brackets'being designated by the numeral 12 and the front ones bynumeral 13. .In' the present instance, the front sill and the side sillsof each of the members 10, 11 are formed of one angle iron, while therear sill is made separately. The angle between the horizontal andvertical webs of the angle irons forming the top framemember 10 facesinwardly and upwardly, while the angle between the webs of the bottomframe member 11 faces inwardly and downwardly. The horizontal webs ofthe members 10 and 11, respectively, are secured by spot welding,

rivets or otherwise to the upper and lower ends of the brackets 12 and13. Each of the front corner'brackets 13 may be of an ularv shape incross section and is provided with flanges 15 at its upper and lowerends to which the horizontal webs of the members 10 and 11 are secured.Extending from the front edges of the-brackets 13 are wings 1,6

which receive the covers for the switchesvis preferably formed of sheetmetal.

are secured to the outside corners of the rear corner brackets 12. Theframework which constitutes the corner irons for the oven comprises twomembers 23 of similar construction and each being formed of an angleiron bent to the shape shown. These members are suitably secured to themem-. ber 20. It will be noted that the back frame extends'upwardly,then laterally, then downwardly, then laterally, and then downwardly,thus providing at the side of the oven a vertical intermediate portion20 to which one of the members 23, constituting a corner iron of theoven, is secured. This provides for simplicity in construction andeconomy in manufacture. The numeral 2-1: designates bracket arms securedto the member 20 and supporting the shelf 9.

From Fig. 3, it will be seen that the legs I) are secured by means ofscrews 21 to anchor members 22 positioned in the corners of the framemember 11 and secured thereto by bolts'25. It will be noted that thelegs may be attached to and detached from the range with great facilityas ready access may be had to the screws from beneath the body portionof the range. The flanges of the frame member 11 conceal the anchormembers 22.

The manner in which the end panels 26 are assembled on the body portionof the frame is shown clearly in Figs. 2 and 5. It W111 seen that theupper and lower edges of the panel 26 are turned inwardly providingflanges 27 and the upper and lower ends of the braces 17 and thebrackets 12 and 13 are notched as at 28 to receive these flanges. Thuseach panel may be very easily assembled by merely bringing the flanges27 into registry with the notches 28 and then pushing the panelinwardly, no other means than friction being provided for securing the.panel in place.

From Figs. 1, 2 and 3, it will be seen that the oven is supported onbrackets 30 and 31 which rise respectively from the cross strut 18 andthe right hand side sill of the member 10. These brackets in one mannerof speaking constitute portions of the framework. At the left hand endof the range 15 a bracket 32 preferably formed of sheet metal and whichaids in supporting the shelf 9. The shelf 9, together with a panel 33rising from the back edge thereof, The edges of the shelf are bent toform a depending skirt 34, and the edges of the panel 33 are bent toform a flange 35 which fits snugly within the portion of the framemember 20 at the left side of the oven. Beneath the shelf 9 and betweenthe brackets 32- and 30is a sheet metal panel 36 the edges of which arealso turned inwardly to provide flanges 36*. One side flange of thispanel" abuts snugly against the'bracket 32 and1 the other engages in arearwardly facing angle formed by a laterally extending flange 37 on thebracket 30. Beneath the oven and positioned between the brackets 30, 31,is a panel 38 similar to the panel 36. These panels may be inserted fromthe back of the range and are held in position by studs or pins 39 inthe rcarwardly extending webs of the brackets 30, 31, and taking intonotches 40 in the flanges of the panels, as most clearly shown in Figs.3 and 4. The top plate 0, preferably formed of sheet metal, is recessedor slotted at its rear edge to accommodate the brackets 30, 31 and thisrear edge is upturned to form a lip 12, as shown in Figs. 1 and 3. Itwill be seen that the lower ends of the panels 36 and extend below theupper edge of the lip l2. If desired, the panels 33, 36 and 38 may bewhite enamclled.

Positioned at the front of the body portion a between the cornerbrackets 13, 13, are. the switches 4% with their fuses as illustrated inmy aforesaid application. It is preferable that the switches and thefuses be enclosed to effect a neat appc'hrance while at' the same timeaccess thereto may be readily had. To this end, there are providedremovable cov'er plates 49 and 50 for the switches and fuses,respectively. The ends of the covers 4-9 and 50 seat'on the wings 16. I

To prevent grease and the like, which may splash onto the top plate,from running down between the hot plates (Z and the edges of theopenings in which they are positioned onthe top plate 0, the edge ofeach of these openings, as most clearly shown in Fig. 3, is bentupwardly to form an upstanding lip 53,-and the hot plates have laterallyextending, downwardly curved flanges 54 covering these lips.

The rear of the back 6 and the oven may be covered over by a sheet orplate of metal 56. The angle iron members of the framework are suitablyapertured, as at 57, to receive theinsulators for the conducting wires(not shown) leading to the hot plates. It will be noted that all of theconducting wires are concealed from view, those for the hot late 9 andthe oven heating unit being led t rough the space provided between therear plate 56 and the panels carried by the back frame.

It is, of course, obvious that the invention 1. In a device of thecharacterdescribed,
